Patent GB-2074403-A (GB)
Title: Emergency light fitting with battery discharge and test facility
IPC: H02J9/06
Filed: 1981-04-16
Abstract: An emergency light fitting 1 is provided with a manual and automatic testing facility 9 whereby at predetermined periods of time an emergency source 2 eg. nickel-cadmium battery, is discharged to a desired level. Each time period is measured by counting mains cycles, and the battery 2 is discharged by connection to a fluorescent lamp 4 through an inverter 5. The fitting is checked during the discharge period. When the battery voltage has fallen to 85% nominal, it is reconnected automatically for charging by the mains. <IMAGE>

Title: Converter included in a phase modulator
IPC: H04L27/20
Filed: 1979-06-08
Abstract: A converter is included in a modulator for phase modulation of data symbols (//c<un>u) and converts the data symbols received each in one time interval to sequences of phase values (//c+//c<un>u). Based on symbol correlation the present phase value sequence is calculated out of an arbitrary rational modulation index, of the present phase state (//c<un>u) which is associated with a first number of symbols previously received and which defines a phase state number, and of a pulse response which extends over the present symbol and a second number of preceding symbols. There exists a finite number of phase value sequences which are stored in digital form in a memory arrangement (MA) and each accessible with an associated address. Any arbitrary sequence of data symbols results in continuous phase transition. A calculating unit (CU) calculates during each time interval a phase state number (v<sn>s). The memory arrangement comprises an access unit to generate the address, which is determined by the present data symbol, by the previously mentioned second number of preceding symbols and by the last phase state number received from the calculating unit.

Patent GB-2102538-A (GB)
Title: Fluid flow control valves
Inventor: LARNER DONALD ALEXANDER
IPC: G05D7/01
Filed: 1981-05-28
Abstract: A pressure compensated flow control valve comprises a valve body 2 defining an inlet 7 and an outlet 11, and a closure member 1 slidably positioned within the body 2. Orifices 9 in the member 1 define part of the main flow path between the inlet 7 and the outlet 11. A rise in inlet pressure moves the member 1 against the action of a spring 3 to restrict flow from the inlet to the orifices 9. Further movement of the member 1 to increase this restriction connects the inlet 7 with the outlet 11 via passage means 16, 17 in the closure member 1. The inlet end of the valve body is adapted to project into the interior of hydraulic system component, e.g. the outlet of a pump. <IMAGE>

Title: Improving the spatial resolution of ultrasonic time-of-flight measurement system
IPC: G01F23/296
Filed: 1981-06-15
Abstract: Where ultrasonic pulses have to be injected into a medium under test via an intermediate medium, such as a container wall where the medium under test is liquid, the pulses acquire an exponentially decaying tail Figure 2 as a result of reverberation in the intermediate medium. This tail is attenuated by delaying the waveform 25 and combining the delayed waveform with the original waveform 24 so as to produce a pulse compression. This improves the effective spatial resolution that can be achieved using the pulses in a time-of- flight measurement system which has to discriminate between multiple signals. The technique may also be used to reduce acoustic background noise and thereby improve signal-to- noise ratio and reduce the minimum usable range. <IMAGE>

Title: Keg handling device
Inventor: LENNON PATRICK
IPC: B66F9/18
Filed: 1981-07-01
Abstract: A lifting device and a mobile keg handling unit which includes such a device has a laterally spaced array of substantially parallel longitudinally extending arms 2 and 3 mounted on a base support 4 which is intended to be carried by the elevatable head of a fork lift truck. Beer kegs are intended to be accommodated in rows between the adjacent pairs of arms 2 and 3 so that upon raising the lift device the arms 2 and 3 abut thickened portions of the beer keg to effect lifting. A ram 11 interconnects the two outermost arms 2 of the array to displace the ends of those arms towards each other to securely retain the beer kegs between the arms. A longitudinally displaceable bar 31 is slidable over the arms 2 and 3 by actuation of hydraulic rams 25 and 29 to displace beer kegs from between the arms 2 and 3. The bar 31 may be displaceable by extension and contraction of a scissors linkage through which it is coupled to the support 4. <IMAGE>

Title: Device in a spreading machine for granular material
Inventor: ANDERSSON STIG GOTE
IPC: A01C15/04
Filed: 1982-08-12
Abstract: In a pneumatic machine for spreading granular material, for example seed or fertilizer, to facilitate testing of the amount of material discharged by the machine, an opening can be caused to appear adjacent the pneumatic ejectors (17) which transport the material to spreading means. The material falls from feeding means (12, 13) into a collecting box (31) placed below the opening, so that the quantity of material discharged can be weighed. When the correct amount of material for a given operation is achieved, the ejector parts (19, 20) are moved to the right by a handle (26), levers (25, 24) and an arm (23) which carries the parts (19, 20). Such movement of the ejector parts closes the opening, after which the machine can be operated for spreading. <IMAGE>

IPC: F16H59/56
Filed: 1982-10-16
Abstract: A vehicle, such as a four wheel drive agricultural or industrial tractor, in which a prime mover (10) drives a gear box (13) which in turn drives first and second pairs of driven wheels (15,11) via first and second drive trains (16,14,18;17,30). Gearbox (13) includes a gear wheel (17) which is axially slidable to effect a ratio change in the gearbox and an axially fixed gear (18) which meshes with the slidable gear (17). A disconnecting means (14) such as a multi-plate clutch is provided in one of the drive trains to disconnect the drive connection with the associated pair of driven wheels (15) during a ratio change which involves sliding of gear wheel (17) thus eliminating inter-tooth friction between the slidable gear wheel (17) and the fixed gear wheel (18) caused by transmission wind-up. The disconnecting means (14) may be actuated in response to movements of a selector means (119) which effects ratio changes in the gearbox or, when a main clutch (12) is provided between the prime mover (10) and gearbox (13), in response to operation of a main clutch control means such as a pedal. <IMAGE>

Title: Adjustable card clip for the recorder
Inventor: EATON WILLIAM CHARLES
IPC: G10D7/03
Filed: 1982-11-15
Abstract: The invention enables players to perform where music stands are either not to hand or inappropriate. The use of the card clip a on a recorder at once puts the music in a sensible playing position and is therefore conducive to good health and improved performance. The music card is adjustable in a channel c to allow for variation in eyesight. This invention allows recorder players to be mobile, with its attendant advantages in the school situation. In the orchestra situation - where a player may be sitting playing one instrument - when a recorder is required it may be simply picked up with the card attached. <IMAGE>

Title: Protecting a powder coating plant against the danger of explosion
Inventor: HOLL WALTER
IPC: B05B5/025
Filed: 1983-02-08
Abstract: To protect a high voltage powder coating plant 10 against the danger of explosion of flash-over due to electrical charging of the articles 18 to be coated, the existence of an arc with an inadmissibly high energy between the articles (18) and their supporting devices (19) is inhibited by applying a test high voltage 24 between the article (18) to be coated and earth (25), before the spray area is reached. Insulation which may be produced by contamination in the earth part 19, 20, 21, 22 is broken down thereby due to an electrical breakdown of lower energy. When the applied voltage is not sufficient to burn off the insulation, the test current falls below a predetermined minimal value (28) which leads to shut down (32) of the plant. <IMAGE>
